“…The above ndings of the present study are further supported by the research work on jute bres; by combining the observation made by Roy et al (2012) and those of Lakshmanan et al (2016). Roy et al (2012) observed that the optimum treatment for producing a strong single Jute ber (610MPa) is 0.5% wt NaOH for 24h at ambient temperature, while Lakshmanan et al (2016) reported that the optimum treatment for producing a strong biocomposite (48.3MPa), with based matrix unsaturated polyester resin, using treated Jute bre is 1%w.t NaOH for 60min at 30°C.…”

[17,18] It is thus observed, that a jute bre treated with a stronger alkaline solution, resulting in a lower tensile strength (25.7 %) but with better contact angle, will produce a stronger bre based composite.…”

“…[4] Jute bre has an increase of 59% in its modulus after being treated with an alkaline treatment of 1% w.t NaOH. [17] The second alkaline treatment (2.5% w.t NaOH for 2 h -SFST) has yielded a bre tensile strength of 117.9 ± 12.3 MPa, about 30 % lower as compared to the optimal NaOH treatment (SFOT). This shows that a higher concentration of the alkaline treatment as compared to the optimum condition produced a treated bre with a lower tensile strength.…”

Composite materials made with synthetic fibres like E-glass, Kevlar or carbon have helped to provide a wide array of products to society with specific engineering properties. However, these materials have a high carbon footprint as well as being non-biodegradable. The use of natural fibre, as a substitution to these man-made fibres, has been studied and encouraging results are being obtained.In this study, the use of ‘Pandanus utilis’ fibre as a reinforcing agent in plastic was investigated with the aim of exploring specific properties such as the tensile strength of the fibre, its wettability and the effect of fibre length after treating the fibre with two different NaOH solutions. Results have shown that better reinforcement was obtained for the composites (11.10 ± 2.53MPa) with fibres subjected to a more aggressive treatment (2.5%NaOH for 2h) compared to the composite made with fibres having maximum tensile strength (168 ± 12MPa at 0.5% NaOH for 14h), due to a better hydrophilicity of the alkaline treated fibre (87.37° internal angle). Within the range of short chopped fibre length tested (6 to 15 mm), it was shown that there was a general decrease in the tensile strength of the composite.

“…In FT, the slower decomposition rate, from 205 • C to 265 • C, shows gradual weight loss whereas the faster rate, from 265 • C to 360 • C, marks active pyrolysis. Maximum weight loss occurred at 325 • C for RT and WT jute fiber [25]. Active pyrolysis was lowest in the case of FT modified jute fiber.…”

In recent years, natural fibers, such as jute has gained significant research interest in order to fabricate fiber reinforced polymer composites. Chemical treatments are generally carried out on the raw fibers for making composites with improved properties. From a composite manufacturing point of view, it is important to understand how the treatments can affect the thermal properties of the jute fiber. In the present research, the effects of rot-retardant, fire-retardant and water-retardant treatments on thermal properties of the jute fiber were investigated. Fiber samples were collected from the middle portion of whole jute fiber. Thermo-gravimetric analysis (TGA) and differential scanning calorimetric (DSC) analysis were subsequently conducted on the jute fiber for thermal characterization. The results demonstrated a lower thermal decomposition temperature in the case of fire-retardant treated jute fiber but higher residue at above 400 °C, as compared to the raw and other treated fibers. In general, it was found that chemically treated fibers absorbed less heat, in contrast to the raw jute fiber and heat flow became negative in all cases of the treated fibers. This study provides important information about the thermal properties of the treated jute fibers for manufacturing polymer-based composite materials.

Doğal lif takviyeli kompozit malzemeler çevre dostu, ucuz ve sürdürülebilir malzemeler olması bakımından endüstride pek çok kullanım alanı bulmaktadır. Bu çalışmada jüt lifi takviyeli ve mantar esaslı sandviç kompozitler üretilerek viskoelastik özellikleri incelenmiştir. Bu amaçla öncelikle jüt lifi/polipropilen (PP) karışımı dokusuz yüzey (nonwoven) kumaşlar ve PP granül kullanılarak ince jüt/PP kompozit plakalar üretilmiştir. Üretilen bu plakalar bir adet mantar levhanın alt ve üst yüzeyine konumlandırılarak basınç altında birleştirilmiş ve sandviç yapılar oluşturulmuştur. Üretilen sandviç yapıların viskoelastik özelliklerini belirlemek amacıyla dinamik mekanik analiz (DMA) testi gerçekleştirilmiştir. Kompozit üretiminden önce liflere uygulanan sodyum hidroksit (NaOH) işleminin kompozit mekanik özelliklerini geliştirdiği gözlemlenmiştir. Üretilen sandviç kompozitlerin inşaat sektöründe yalıtım malzemesi olarak ve ofis alan ayırma panellerinde, aynı zamanda otomotiv endüstrisinde kullanımı amaçlanmaktadır. Natural fiber reinforced composite materials have found many applications in various industries due to the fact that they are naturefriendly, low-cost and sustainable materials. In this study, jute fiber reinforced and cork based sandwich composites were produced and their viscoelastic properties were investigated. First, thin jute/polypropylene (PP) composite plates were produced by using jute/PP nonwoven fabrics and PP granules. Then these plates were placed on top and bottom faces of a cork plate and consolidated under pressure to produce sandwich composites. Dynamic mechanical analysis (DMA) was performed to determine the viscoelastic properties of the produced samples. It was found that sodium hydroxide (NaOH) treatment of fibers before composite preparation lead to higher mechanical properties of the composites. The produced sandwich composites can be used in construction industry as insulation materials and office partition panels as well as in automotive industry.
